Many other naturally occurring amino acids exist, and the structures of a few of these are displayed below. Some, such as hydroxylysine and hydroxyproline, are simply functionalized derivatives of a previously described compound. These two amino acids are found only in collagen, a common structural protein. Homoserine and homocysteine are higher homologs of their namesakes. The amino group in beta-alanine has moved to the end of the three-carbon chain.

Metamorphic grade refers to the temperature and pressure under which a rock was metamorphosed, considered low grade or high grade. Since metamorphic minerals in a rock form under specific. conditions, they are used to identify the temperature and pressure of the metamorphic conditions. Metamorphic rock fabrics and textures. Foliated rocks have a âfabricâ, called a foliation, caused by the parallel alignment of mineral grains.
