transmit signal across a synapse to t he dendron of the next neurone. Most neurotransmitters are about the size of a single amino acid but some of them may be the size of larger pro teins or peptides. Types of neurotransmitters the main neurotransmitters are amino acids‚ amines ‚peptides‚ and certain soluble gases. Amino acids: glutamate‚ aspartate(Aspartic acid )‚ glycine( 甘氨酸 ) Amines( 胺 ): dopamine( 多巴胺 )(DA)‚ norepi nephrine (noradrenaline; NE‚ NA)‚ epinephrin e (adrenaline)‚ histamine

Review 2: Text DNA is a very special and important molecule that is in our life‚ DNA is found in the nucleus. DNA stores the data needed to make poly peptides‚then data in a nucleic acid is transferred to messenger RNA‚ which escapes the nucleus into a protein. According to the DNA and protein article DNA is used in many things but DNA is used to make pol-peptides. They are another word for proteins. When a cell makes a protein the direction are resembled from the part of an DNA. DNA strand and transcript

What are the positive and negative effects of creatine? Creatine is a naturally occurring amino acid that’s found in meat and fish‚ and also made by the human body in the liver‚ kidneys‚ and pancreas. It is converted into creatine phosphate or phosphocreatine and stored in the muscles‚ where it is used for energy. During high-intensity‚ short-duration exercise‚ such as lifting weights or sprinting‚ phosphocreatine is converted into ATP‚ a major source of energy within the human body.Creatine supplements

are characterized by three fundamental structural requirements: the fused beta-lactam structure (shown in the blue and red rings‚ a free carboxyl acid group (shown in red bottom right Figure1.1)‚ and one or more substituted amino acid side chains (shown in black). The lactam structure can also be viewed as the covalent bonding of pieces of two amino acids - cysteine (blue) and valine (red). Fig. 1.1: Penicillin – Beta Lactam Structure In terms of functional groups‚ the penicillin has 4 different

Proteins are a diverse group of macromolecules with many different functions (Mbuthia‚ 2012). Many are structural components of bone‚ muscle‚ hair‚ tissue‚ etc. Others are enzymes that speed up cellular reactions. All proteins are made up of amino acids (Johnson‚ 2010). The purpose of this experiment is to determine whether peptide bonds are present in various food substances. The color violet will indicate the presence of proteins. The more intense the color is‚ the greater number of peptide bonds
