we have to take every day‚ therefore we would like to identify the types of macromolecules that contain in some of the food or solution in order to maintain a healthy life. There are four groups of macromolecules which are carbohydrates‚ lipids‚ proteins and nucleic acid. They are mostly made up of hydrogen‚ carbon‚ oxygen‚ nitrogen‚ sulphur and phosphorus. 1. Carbohydrates Carbohydrates are organic compounds that with the combination of carbon‚ hydrogen and oxygen in a 1:2:1 ratio. Carbohydrates

synthesis of proteins. [1] They are very large molecules built from subunits called nucleotides. All nucleotides have a common structure: a phosphate group linked by a phosphodiester bond to a pentose (a five-carbon sugar molecule) that in turn is linked to an organic base. [2] Figure 1. General structure of a nucleotide One type of nucleic acid is the ribonucleic acid (RNA). The RNA is single-stranded used for the coding of the primary sequence of amino acids to make proteins‚ and is found

Plasma Membrane: This organelle’s main function is to protect the cell from its surroundings‚ the membrane also regulates the movement of substances that go in and out of the cell. This is composed of phospholipid bilayer with embedded proteins. Cell Wall: The cell wall is composed of cellulose‚ this sugar is used as structure and protection. This organelle is only found in plants. The cell wall has three layers the middle lamella‚ primary cell wall‚ and secondary cell wall. The middle lamella contains

polar * Amino (Amines): Acts as a base; can pick up an H- from the surrounding solutions (water‚ in living organisms) * Sulfhydryl (Thiois): Two sulfhydryl groups can react‚ forming a covalent bond. This “cross-linking” helps stabilize protein structure *

through the plasma membrane because of pressure or concentration differences between the interior and exterior of the cell. Facilitated diffusion relies on carrier proteins‚ and occurs when molecules are either not lipid soluble or are too large to pass through the pores of the membrane. Solutes have to combine with the carrier proteins in the membrane‚ and then they can be transported down the concentration gradient. Filtration is the movement of solute and water molecules across a membrane due

The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

What is a gene?‚ 2015)Genes lie in long strands of deoxyribonucleic acid (DNA) called chromosomes. DNA containing genes form structures call chromosomes. Humans have 23 pairs of chromosomes. Chromosomes are made up of a single molecule of DNA and proteins. (Medicine‚ 2015) DNA is a double-stranded molecule compose with sugar‚ phosphate and four nitrogen bases called nucleotides. They are A (Adenine)‚ C (Cytosine)‚ G (Guanine) and T (Thymine). These bases

Actin‚ a globular protein with a molecular weight of 42-kDa‚ is the most abundant intracellular protein in most eukaryotes (3). It plays important roles in many essential cell biological processes. Actin exists as a monomer called G-actin and as a filament called F-actin‚ a linear chain of G-actin subunits (2). Two F-actin filaments intertwine to form a microfilament‚ one of the three major components of cytoskeleton (2). Microfilament is important for generating cell movement. One mechanism involves

don’t interface well. The hydrophilic Asparagine would be repulsed by the hydrophobic amino acids; they would every attempt to detach the other with a specific end goal to be "upbeat". In the event that they are not cooperating‚ the strength of the protein would waver in light of the fact that the amino acids would be repulsing one another and incapacitate it from working
