Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle amino acids by structure, classification, biological role, nutrition and supplements, with care about health claims.

An organic compound containing an amino group and a carboxylic acid group; about 20 proteinogenic amino acids are the building blocks of proteins, and many others have biological or industrial roles.

What it is for: Building proteins, metabolism, signalling and nutrition.

It can be classify amino acids; explain protein structure; understand essential amino acids in diet; assess supplement claims.

Distinguishing features

Amino plus carboxylic acid group

Chiral (except glycine)

Build proteins

Some are essential in diet

What it looks like

White crystalline solids when pure.

How it is recognised

Amino and carboxyl groups

Three- and one-letter codes such as Val and V
