Alkanes are named based on the number of carbon atoms in their longest continuous chain. The prefix used in the name corresponds to the number of carbon atoms in the chain (e.g. meth- for one carbon atom, eth- for two carbon atoms, prop- for three carbon atoms). The suffix -ane is added to indicate that the compound is an alkane. Additionally, any branches or substituents on the carbon chain are named using prefixes such as methyl-, ethyl-, etc. **

Enzymes are named based on the type of reaction they catalyze and the substrate they act upon. The names of enzymes typically end in "-ase" to indicate their enzymatic function.

Additionally, enzymes are often given a systematic name based on their specific function and the biochemical pathways they are involved in. **

Angles are named based on the relationship between the rays that form them. The most common way to name an angle is by using three points, with the middle point representing the vertex of the angle. For example, an angle can be named as ∠ABC, where A and C are the endpoints of the rays that form the angle, and B is the vertex. Another way to name angles is by using a number or letter to represent the angle itself, such as ∠1 or ∠x. **

However, it is important for these products to be clearly labeled as vegan to avoid confusion and ensure transparency for consumers. **
