dual-function gland‚ having features of both endocrine and exocrine glands. The part of the pancreas with endocrine function is made up of approximately a million[3] cell clusters called islets of Langerhans. Four main cell types exist in the islets. They are relatively difficult to distinguish using standard staining techniques‚ but they can be classified by their secretion: α cells secrete glucagon (increase glucose in blood)‚ β cells secrete insulin (decrease glucose in blood)‚ delta cells secrete

IMP 2 POW 3: Divisor Counting. I. Problem statement: This POW is all about finding information and patterns about the way divisors of certain numbers are found and expressed. In this POW when we talk about divisors we usually are counting the number of divisors that a number has. The divisor is a number that a number can be divided by‚ of course every number is divisible by every other number but in these problems we are only talking about whole‚ positive numbers. Every number is divisible evenly

Mechanism 4 shows the debromination of 2α-bromocholestan-3-one to give 4. This mechanism which is similar to a Favoskii rearrangement‚ is likely to go via this path as other research has shown that there is often a by-product with this reaction. The by-product is cholest-4-en-3-one which requires the intermediate seen in the third molecule in the above mechanism. The intermediate is highly strained and with the presence of base a proton will be extracted which aids the collapse of the three membered
