A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.

The smallest molecule is diatomic hydrogen (H2), with a bond length of 0.74 angstroms.

isoleucine

protein titin

The IUPAC name for Titin. This is thelargest known protein and so has the longest chemical name. Written in full, it contains 189,819 letters….What is the longest chemical formula?

Euler’s identity is an equality found in mathematics that has been compared to a Shakespearean sonnet and described as “the most beautiful equation.” It is a special case of a foundational equation in complex arithmetic called Euler’s Formula, which the late great physicist Richard Feynman called in his lectures “our …

Mathematics writer Constance Reid has opined that Euler’s identity is “the most famous formula in all mathematics”.

K (required argument) – This is an integer that specifies the position from the largest value in the array or range of cells of data to return.

Array (required argument) – This is an array or range of numerical data for which we want to find the k smallest value. K (required argument) – This is the smallest value from the given array.

The Excel LARGE function returns numeric values based on their position in a list when sorted by value. In other words, it can retrieve “nth largest” values – 1st largest value, 2nd largest value, 3rd largest value, etc. Get the nth largest value. The nth largest value in the array.

Excel COUNTIFS Function

1. Summary. The Excel COUNTIFS function returns the count of cells that meet one or more criteria.
2. Count cells that match multiple criteria.
3. The number of times criteria are met.
4. =COUNTIFS (range1, criteria1, [range2], [criteria2].)
5. range1 – The first range to evaulate.
